[Po4a-devel]Sgml module does not translate the lang attribute

I am putting po4a in place for the translation of the Wine documentation. Pretty much the only issue is that the text generated by DocBook itself, 'Table of Contents' for instance, is not translated. The reason is that the language to use for this text is defined by the 'lang' attribute as in: <book lang="en"> ... </book> But the value of the lang attribute is passed as is by po4a-translate. I checked the Sgml.pm module and indeed it does not have any provision for translating attributes :-( It looks like it should be done near this code (line 680): if ($val->type() eq 'CDATA' || $val->type() eq 'IMPLIED') { if (defined $value && length($value)) { if ($value =~ m/"/) { #" $value = "'".$value."'"; } else { $value = '"'.$value.'"'; } $tag .= ' '.lc($attr).'='.$value; } Unfortunately that's as far as I got and now I don't have any idea on how to modify this code to add this functionality. Maybe if someone can provide me some pointers... -- Francois Gouget fgouget(a)free.fr http://fgouget.free.fr/ May your Tongue stick to the Roof of your Mouth with the Force of a Thousand Caramels.
